DATASHEET Ɩ EM8504 POWER MANAGEMENT CONTROLLER WITH ENERGY HARVESTING INTERFACE Description The EM8504 is an integrated power management solution for low power applications. It is specifically designed for efficient operation with Dye-Sensitized Solar Cells (DSSC) in the µW to mW range. To optimize harvesting efficiency, the EM8504 incorporates a maximum power point tracking (MPPT) controller based on a fixed Voltage at Maximum Power Point (VMPP). The device is designed to speed-up system start-up time when the main energy storage element (aka Long Term Storage – LTS) is completely discharged or insufficiently charged to supply the application, by using a secondary energy storage element (Short Term Storage - STS).
